Pickers

Pickers provide a simple way to select a single value from a set. In addition to touching the
up/down arrow buttons, it's possible to set the desired value from the keyboard or via a swipe
gesture.

Space considerations

Pickers can be used inline on a form, but their relatively large footprint is best suited for
display in a dialog. For inline display, consider using more compact controls such as text fields or
spinners.

Date and time pickers

Android provides these as ready-to-use dialogs. Each picker is a dialog with a set of controls for
entering the parts of the date (month, day, year) or time (hour, minute, AM/PM). Using these in your
app helps ensure that a user's specification of a data or time input is valid and formatted
correctly. The format of a time and date picker adjusts automatically to the locale.
